Answer:
The second ramp needs to have 25°.
Step-by-step explanation:
Required ramp angle for driving the car from the ground = 35°.
First ramp angle = 15°
Therefore, second ramp angle equals required ramp angle minus first ramp angle, which is = 35° - 15° = 20°
The 20° ramp angle will make the total ramp angle to be equal to 35°.
That is 15° + 20° = 35°
Answer: 30 pairs of shorts
21x+420=35x
subtract 21x from both sides of the equation.
420=14x
get rid of the x by division
420/14
you get 30 =x
Answer:
There are 10 two point questions and 16 five point questions.
Step-by-step explanation:
- x = the number of 2 points questions
- y = the number of 5 points questions
- x + y = 26
- 2x + 5y = 100
- x = 10 two points questions
- y = 16 five points questions
